TCP/IP Networking Suite

The full TCP/IP Networking Suite is specifically written for small, ARM and Cortex-M processor-based microcontrollers. It is highly optimized, has a small code footprint, and gives excellent performance.

Using TCP/IP Networking suite

Programs are written using standard C constructs and compiled with the ARM Compilation Toolchain provided in the MDK-Professional. Applications using the TCP/IP networking suite only require that you include a special header file and link your program with the libraries included in MDK-Professional.

Note:

The TCP/IP Networking Suite is provided in binary form as part of MDK-Professional. It is not included with other MDK-ARM Editions.

Benefits

Full Networking Suite - The TCP/IP Networking Suite provides comprehensive support for transmission protocols such as TCP/IP and UDP, as well as application level services and clients including HTTP, Telnet, SMTP, SNMP, FTP, and many others. Unlike other TCP/IP stacks, it includes all these features as standard. There are no hidden costs and you do not have to pay extra as you add additional functionality to your system.

Flexible Memory Footprint - The TCP/IP Networking Suite has been optimized for use in MCU-based systems and uses the minimum system memory. Its footprint size depends on which parameters you choose to build into your application.

Easy to Use - The TCP/IP Networking Suite is easy to customize for each application you create using the configuration wizard.

Standalone Operation - The TCP/IP Networking Suite integrates into your software architecture, and can be used as a standalone C library. There is no necessity to use it with an RTOS. However, there are significant benefits for using an RTOS in modern embedded systems.

Source Code - The TCP/IP Networking Suite is available as source code on request. This is useful where source code is needed for product certification.

Scalability - Applications are easy to design, maintain, and expand. Libraries can be used and re-used in multiple applications.

Royalty-Free - The TCP/IP Networking Suite is supplied Royalty-Free. Once licensed you can ship products created using the TCP/IP Networking Suite with no further fees or on-going costs.
